Montserrat Volcano Observatory

Morning Report
Report for the period 4 pm 21 Julyto 7 am 22 July 1997

The alert level system has been revised by zones

The volcano has continued with about the same level of activity as
yesterday. The only seismic signals currently being recorded are small to
moderate amplitude rockfall signals. Further rockfalls and moderate
pyroclastic flows can be expected later today, and may occur in any
direction at any time.

The volcano cleared sufficiently at about 5:00 am today to allow three
chutes of incandescent material to be clearly visible from the MVO. These
were observed to originate from the top of the dome above the Gages valley,
Mosquito Ghaut and further east. The volcano is overcast this morning but
prospects look good for clear views later during the day.

The current area of activity in the crater still makes Mosquito Ghaut and
Gages the most likely pathways for pyroclastic flows and surges, but
further flows in Tuitt's or Tar River are possible. The Belham River valley
is also dangerous and should not be entered. Access to the exclusion zone
is completely restricted, and people should stay completely away from the
flanks of the volcano. Everyone should continue to stay alert, and listen
to Radio Montserrat for any announcements.
